Before European contact, Torrey Hills was on a prehistoric trade route between the
Kumeyaay trade village of Ystagua in
Sorrento Valley and Ahwel-Awa in San Dieguito on the way to the
Payómkawichum tribe in the north, which was adopted to become part of the
El Camino Real under the
Spanish. In 1979 when Carmel Valley was being planned, the city had conducted studies on the
Los Peñasquitos Canyon Preserve as an
open space park, but had not determined the boundary of the park. The city then designated Sorrento Hills (now Torrey Hills) as Future Urbanizing on the General Plan. In February 1980, Genstar-Peñasquitos (now AG Land Associates, LLC) dedicated a total of of Los Peñasquitos Canyon to the city. This created a border for the preserve. As a result, a community planning program was initiated, and the original plan area was transferred from Future Urbanizing to Planned Urbanizing on the General Plan, excluding adjacent to the Sorrento Hills community planning area, which was designated as Future Urbanizing. ==Education==
